LOCKING-IQUOIN FOR PRINTERS GALLEYS.

SPECIFICATION forming part of Letters Patent No. 642,890, dated February 6, 1900.

Application filed August 16, 1899. Serial No.727,3 71. (No model.)

To whom it may concern:

Be it known thatI, GEORGE ASSENMACHER, acitizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Locking-Quoins for Printers Galleys, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to locking-quoins for printers chases or galleys; and the object thereof is to provide an improved device of this class by means of which type may be securely locked in a chase or galley. In the present state of the art it is customary to provide devices of this class consisting of two oblong blocks the adjacent faces of which are inclined from one end to the other and the opposite faces parallel. With this form of .quoin or wedge, however, the separate blocks have a tendency to slide one upon another when pressure is applied to the parallel sides or faces, and this operation results in loosening the type in the chase or galley, and it is this objection that the present invention is designed to obviate.

Another object of this invention is to provide improved means for operating quoins or wedges of the class described, and with these and other objects in View the invention consists in a quoin or wedge lock for the purpose specified,constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same numerals of reference in each of the views, and in which- Figure 1 is a side view of a device constructed according to my invention; Fig. 2, a transverse section thereof on the line 2 2, and Fig. 3 a side view of an implement which I employ in the manipulation of my device.

Referring more particularly to the drawings, I have shown a device for use in connection with printers chases or galleys which comprises two oblong blocks 4 and 5, each of which is provided with a plane longitudinal face 6 and a broken longitudinal inclined face 7, which consists of a series of planes 8, parallel with the face 6 of the same member, and a series of intermediate inclined shoulders 9, by which said parallel planes 8 are connected. The planes 8 and shoulders 9, forming the longitudinal faces 7 of each of the members 4 and 5, exactly coincide in form.

Arranged upon the longitudinal face 7 of the member at is a longitudinal rib or strip 10, preferably set into a groove therein cut through the planes 8 and shoulders 9, and the member is provided with a corresponding longitudinal recess 11, formed to exactly receive the strip 10, and the strip 10 and recess 11 are of such form and dimensions that the faces 7 ofthe two members4 and 5 may snugly coengage.

Each of the members 4: and 5 is provided upon one side with a plurality of recesses 12, the number of recesses upon the member 5 being, preferably, in excess of that upon the member 4, and the said members may be relatively moved by means of an implement which I have devised which operates in connection with said recesses and the construction of which, referring to Fig. 3, is as follows: A shank 13 is provided with a contracted end portion 14, which is bifurcated so as to form two parallel prongs 15. A crosshead 16 is secured centrally to the opposite end of the shank 13 and provided at one end with a knob or head 17. In the practice of my invention I grasp the cross-head 16, and, having previously placed the members 4 and 5 of the device illustrated in Figs. 1 and 2 in operative position between the made-up form and the printing side or end of the chase or galley, I pass the prongs each one into a recess in each of the members 4 and 5, tighten, and thus securely clamp the form in the chase or galley. The planes 9 of the faces 7 of said members operate to wedge the latter apart, the planes 8 operating as intermediate stops, and when said planes 8 of both members are in engagement there will be no tendency of the members to move relatively under pressure on the parallel sides thereof. The knob 17 may, if desired, be used as a hammer-head to drive the members 4 and 5 or to adjust them in various ways.

It is evident that I may make many alterations in the construction and arrangement of the parts of my invention without departing from the spirit thereof, and that my improved device may be applied in a variety of connections and for a variety of purposes similar to that set forth, and such applications may still come within the scope of my invention.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. The herein-described device, comprising two oblong blocks which are placed side by side, and the adjacent faces of which are inclined from end to end, and the opposite faces parallel, the inclined faces being provided with separate spaces parallel with the parallel sides, substantially as shown and described.

2. The herein described device, comprising two oblong blocks which are placed side by side, and the adjacent faces of which are inclined from end to end, and the opposite faces parallel, the inclined faces being provided with separate spaces parallel with the parallel sides, and connected by sliding inclined shoulders, substantially as shown and described.

3. The herein-described device, comprising two oblong blocks which are placed side by side, and the adjacent faces of which are inclined from end to end, and the opposite faces parallel, the inclined faces being provided with separate spaces parallel with the parallel sides, and connected by inclined shoulders, and means for moving said blocks longitudinally, substantially as shown and described.

4. The herein-described device, comprising two oblong blocks which are placed side by side, and the adjacent faces of which are inclined from end to end, and the opposite faces parallel, the inclined faces being provided with separate spaces parallel with the parallel sides, and connected by inclined shoulders, and means for moving said blocks longitudinally, consisting of cavities or recesses formed in the top faces thereof and adapted to receive the prongs of a key, substantially as shown and described.

In testimony that I claim the foregoing as my invention 1 have signed my name, in presence of the subscribing witnesses, this 14th day of August, 1899.

GEORGE ASSENMACHER.
